Nyob rau hauv Soviet thiab tom qab-Soviet lub sij hawm, kev tsim kho tsis tau xyuam xim rau zoo thermal rwb thaiv tsev ntawm chav tsev, tsim nyog yuav tau txuag rau cua sov. Raws li qhov tshwm sim, "Stalinka", "Khrushchev" thiab lwm lub tsev ua tau raws li cov cuab yeej qub qub tau txias txias rau lub sijhawm ntev, tshwj xeeb tshaj yog cov ces kaum ntawm cov tsev siab. Kev loj hlob sai ntawm kev tsim kho kev lag luam tau ua rau muaj kev nthuav dav ntawm cov khoom siv ntau yam.
tsoos rwb thaiv tsev
Nyob rau hauv lub lig 90s, ntxhia wool, iav ntaub plaub thiab lwm yam cellulose-raws li rwb thaiv tsev tau nrov heev li rwb thaiv tsev. Txawm tias muaj cov yam ntxwv zoo thermal rwb thaiv tsev, lawv ploj mus rau hauv keeb kwm yav dhau. Qhov no yog vim qhov loj me ntawm cellulose fiber boards, uas txo qhov muaj txiaj ntsig zoo hauv chav tsev, nrog rau qhov tshwm sim ntawm cov ntaub ntawv tshiab, xws li rwb thaiv tsev ua kua. Kev tshuaj xyuas ntawm cov neeg tsim kev paub txog thiab cov pej xeem zoo tib yam pom zoo tias cov khoom siv zooua nws txoj haujlwm. Nyob rau tib lub sijhawm, kev rwb thaiv tsev cellulose tseem nrov heev vim nws tus nqi qis, kev ua haujlwm yooj yim thiab kev phooj ywg ib puag ncig.
Kev xaiv cov khoom siv thermal rwb thaiv tsev
Xaiv lub rwb thaiv tsev zoo yog qhov yuav tsum tau ua ua ntej los tsim kom muaj lub tsev sov thiab xis nyob. Nws yuav tsum muaj cov khoom nram qab no: dej nqus, thermal conductivity, vapor permeability, hluav taws kub. Kev xaiv ntawm rwb thaiv tsev yog nyob ntawm cov khoom siv los ntawm cov vaj tsev tsim, cov xwm txheej huab cua, tus naj npawb ntawm storeys thiab loads ntawm lawv. Muaj ntau cov ntaub ntawv rau kev rwb thaiv tsev sab hauv ntawm chav tsev. Ib qho zoo tshaj plaws yog kua phab ntsa rwb thaiv tsev. Kev tshuaj xyuas ntawm cov neeg tsim khoom lees paub nws qhov zoo.
Yuav ua li cas rwb thaiv tsev yog dab tsi?
Kev lag luam niaj hnub no yog tag nrho ntawm cov khoom lag luam los ntawm ntau lub tuam txhab, suav nrog txhua yam ntawm cov cua sov. Cov rwb thaiv tsev ua kua yog siv ob qho tib si sab nraud thiab sab hauv lub tsev, yog li ua kom muaj kev sib hloov hluav taws xob zoo (nws khaws cov cua sov hauv lub caij ntuj no thiab txias thaum lub caij ntuj sov). Nyob rau tib lub sijhawm, nws tiv thaiv chav los ntawm kev nkag mus ntawm noo noo, tsim ntawm corrosion thiab pwm, thiab tshem tawm qhov muaj peev xwm ntawm condensation nyob rau hauv cov ces kaum. Feem ntau, kev siv cov ntaub ntawv thermal rwb thaiv tsev tuaj yeem txuag tau cov nqi cua sov.
Ua kua thermal rwb thaiv tsev yog ib qho kev daws teeb meem niaj hnub uas tso cai rau tsis tsuas yog ua kom muaj cov thermal rwb thaiv tsev zoo hauv chav, tab sis ua kom nws ntxim nyiam dua. Cov khoom muaj ib tug tshwj xeeb pasty sib xws,ua tsaug uas nws tuaj yeem siv tau yooj yim rau qhov chaw nkag tsis tau tshaj plaws.
Ua kua rwb thaiv tsev yog tsim los ntawm cov kua roj vanish thiab dej. Rau kev siv sab hauv tsev, cov rwb thaiv tsev dej yog siv, thiab hauv kev ua haujlwm qis dua 0 C, nws yog kua roj vanish. Nws tsis yog qhov tsim nyog los siv cov kev pabcuam ntawm cov kws tshaj lij rau kev rwb thaiv tsev hauv tsev, txij li cov txheej txheem yog qhov yooj yim thiab tsis xav tau kev paub tshwj xeeb.
Khoom specifications
Cov rwb thaiv tsev muaj qhov sib xws ntawm pasty thiab muaj adhesion zoo, vim nws yog siv rau txhua txheej: pob zeb, cib, hlau lossis yas. Tus txheej txheem txheej thickness yog 1 hli. Qhov tshwm sim ntawm kev ua haujlwm yuav tsum yog cov txheej txheem ruaj khov thiab elastic uas tuaj yeem tiv taus qhov kub thiab txias tsis muaj kev tawg. Nyob rau tib lub sijhawm, nws tsis kub hnyiab, tsis tso cov tshuaj phem rau kev noj qab haus huv, thiab tseem muaj dej thiab vapor nruj. High-quality kua thermal rwb thaiv tsev muaj peev xwm ua tau nws cov dej num mus txog 20 xyoo. Siv ob peb lub tsho tiv no tuaj yeem nce qhov kub hauv tsev los ntawm 2-4 C thaum lub caij ntuj no.
Nyob zoo ib tsoom niam txiv kwv tij neej tsas sawv daws.
Ua kua rwb thaiv tsev hauv lub tog raj kheej muaj ntau qhov zoo:
- kev teeb tsa yooj yim - feem ntau siv nrog txhuam;
- txo cov nqi hluav taws xob los ntawm 25-30%;
- rwb thaiv tsev tsis hloov qhov pom ntawm vaj tse;
- nqi qis. Rwb thaiv tsev nrog cov ntaub ntawv vaj huam sib luag yog 30-40% kim dua;
- ua haujlwm tuaj yeem pib yam tsis muaj kev npaj ua haujlwm (qhov saum npoo yuav tsum tau ntxuav ntawm plua plav, qee zaum muab tso);
- rau ib tus neeg ua haujlwmhnub yog insulated mus txog 100 m 2 nto.
Flaws
hom rwb thaiv tsev no kuj muaj qee qhov tsis zoo:
- rhiab rau qhov tsis raug thiab kev thauj mus los, lub neej luv luv;
- kwv nqi siab;
- tuam txhab tsim khoom tsis muab cov ntaub ntawv tseeb txog cov thermal conductivity ntawm cov khoom thiab cov txheej txheem rau lawv cov kev suav;
- cov rwb thaiv tsev zoo qee zaum xav tau txog 12 txheej ntawm cov khoom.
- Feem ntau noj ntau dua li qhov qhia los ntawm cov chaw tsim khoom.
Daim ntawv thov
Cov ntaub ntawv rwb thaiv tsev yog siv rau saum npoo, yav tas los ntxuav ntawm cov av. Yog tias cov xim qub tseem nyob ntawm nws, ces nws kuj raug tshem tawm. Hlau nto puas tsuaj los ntawm corrosion yog kho nrog ib tug tshwj xeeb xeb converter (ib yam khoom raws li phosphoric acid). Ua ntej siv, cov rwb thaiv tsev yog diluted mus rau lub xeev tuab. Qhov sov ntawm qhov chaw, cov khoom ua kua ntau dua tuaj yeem ua tau. Qhov saum npoo yog npog tib yam li cov xim yooj yim.
Ua kua phab ntsa rwb thaiv tsev polymerizes hauv 24 teev. Rau kev ua m2 nto hauv 1 txheej, 1 liter ntawm cov khoom yuav tsum tau. Qhov nruab nrab, 5-6 txheej yuav tsum tau siv. Cov khaubncaws sab nraud povtseg ntau dua, chav tsev zoo dua yuav khaws cov cua sov. Cov txheej txheej zoo nkauj, xws li plaster, tuaj yeem siv rau cov rwb thaiv tsev.
Ntau manufacturers
Cov npe nram qab no ntawm lub tshuab cua sov yog muaj nyob rau hauv kev lag luam hauv tsev:
- nrov tshaj plaws yog Corundum. Qhov no ua kua phab ntsa rwb thaiv tsev muaj siab adhesion thiab tsis kam mus rau txhua yam ntawm sab nraud influences. Lub thickness ntawm ib txheej yog tsawg dua 1 hli. Cov khoom siv tau zoo thiab tus nqi siab - 1 liter tus nqi 350-600 rubles;
- "Astratek" yog ib qho kev tiv thaiv ib puag ncig nrog kev tiv thaiv corrosion. Lub sijhawm ntev ntawm kev ua haujlwm yog ib qho tshwj xeeb uas cov kua rwb thaiv tsev no muaj. Kev tshuaj xyuas ntawm cov neeg tsim khoom paub meej tias nws cov kav ntev - 30 xyoo. Tus nqi ntawm cov khoom yog 400-500 rubles / l;
- "Akterm" yog lub rhaub nrog cov thermal efficiency. Ib txheej 1 hli tuab yog sib npaug rau 5 cm txheej ntawm ntxhia wool. Cov khoom muaj lub sijhawm lav ntawm 15 xyoo. Nws yog tsim nyob rau hauv ob peb variations: "Standard" (dej-raws li), "Nord" (nitro-based), "Facade", siv rau ntoo thiab cib, "Anticor" - rau hlau coatings. Nws mus muag hauv 10 thiab 20 l thoob. Tus nqi ntawm 1 liter yog 320 rubles. Thermal rwb thaiv tsev tuaj yeem siv rau hauv qhov kub ntawm -60 txog +600 C;
- "Teplometta". Raws li cov chaw tsim khoom, txheej txheej ntawm 1 hli yog sib npaug rau 5 cm ntawm cov ntxhia wool thiab 2.5 cm ntawm nthuav polystyrene. Cov khoom siv tau yooj yim tinted, nws tuaj yeem siv rau qhov kub tsis qis dua -20 C. Cov rwb thaiv tsev muaj ntawv pov thawj lees paub tias nws ib puag ncig kev nyab xeeb.
Cov Lus Qhia Tus Kheej
Cov ntaub ntawv rwb thaiv tsev tuaj yeem siv rau saum npoo nrog cov tshuaj tsuag tsis muaj cua. Lub thermal rwb thaiv tsev nyhuv yog nyob rau hauv qhov tseeb hais tias lub rwb thaiv tsev yog ib tug ntxeem tau txheej,qhov chaw sab hauv uas yog nyob rau hauv ib tug rarefied lub xeev. Nws txo qis kev hloov pauv cua sov.
Qhov smoother ntawm qhov chaw, qhov kev siv hluav taws xob qis dua. Piv txwv li, nws yuav siv qhov kev txiav txim siab ntau dua los ua cov phab ntsa cib dua li ua cov pob zeb tiaj tus. Yog tias cov rwb thaiv tsev yuav raug siv rau qhov chaw nqus dej (pob zeb, cib thiab lwm yam), tom qab ntawd lawv yuav tsum tau ua ntej nrog cov xim acrylic.
